Modern cars are equipped with multiple safety features to make sure the right key is used to turn the engine. Only certain engines can use car keys that are specifically coded for this purpose. The engine will not start even if the key is copied and turned on by someone else.

Without the correct key, it is very difficult to turn the engine of modern cars. An ignition switch warning light is included on most cars to alert you if an ignition problem has occurred.

 

Why is the Ignition Key Warning Light On?

Depending on your vehicle, the warning light could mean many things. This light indicates a problem in the ignition key, or with the key being used. The problem with the ignition keys is often mechanical. It prevents the key turning. It could be due to a worn or damaged roller mechanism, a key, dirt or debris in the mechanism that is preventing it from turning. While you can clean the keyhole, it is possible to replace the lock or replace the key.

The possibility exists that the key could be checked for longer if this light is on while you are driving. This is usually caused by a computer glitch and can happen in rare cases. The vehicle won’t start if the key is invalid. If this happens, the vehicle should be taken to the nearest service center immediately. If the key is in good condition, the problem can be reprogrammed.

This light can be illuminated in two different colors on some models. If the light is yellow, it means that there is a problem in the ignition switch. Even if the car is stopped, it can still start (although there is always the possibility of it not starting). If the red light is on, it means that you can’t start the car if you stop it.
